Yeah, the critical part for me on that is "no", which sounds like the microaggression is a rejection of whatever cultural identity she's claimed.Okay, stepping my foot in it in hopes that I come out of this less stupid: what's the deal with the "you're white" one? I can imagine contexts in which it becomes offensive (i.e. "that can't be your dad, you're white" or "what do you mean you celebrate kwanza with your bi-racial family, you're white") but I can see others where I would still say or think that at someone and think that I was in the right. I mean, that girl holding the sign is whiter than the snow in Vermont. She may have a biological parent that's another race, or she might be the whitest person in Mexico, or she might be adopted into a family of another race, but that is not the face of a person who is going to see a lot of racial discrimination in her lifetime. She's not going to get pulled over for driving while black. No one is going to assume she's a terrorist at the airport (any more than the norm).
I dunno. I'm stuck on that one, which probably means I'm wrong about something.
Most likely it's that she's mixed-race and just happened to get mostly pale pigmentation. My son is the same way; doesn't identify as white, but has pale skin and blue eyes.
It's only offensive if someone insists that you're white even though you've told them your nonwhite racial or ethnic identity. I've had people do that to me, or tell me that I "don't HAVE to tell people" I'm part Black, because "no one would ever know".
Still, I tend not to assume that someone's white unless they tell me they are.
